Question

我的adapter.xml

<?xml version="1.0" encoding="UTF-8"?>
<wl:adapter name="DbConnect"

    <displayName>DbConnect</displayName>
    <description>DbConnect</description>
    <connectivity>
        <connectionPolicy xsi:type="sql:SQLConnectionPolicy">
            <!-- Example for using a JNDI data source, replace with actual data source name -->
            <!-- <dataSourceJNDIName>java:/data-source-jndi-name</dataSourceJNDIName> -->

            <!-- Example for using MySQL connector, do not forget to put the MySQL connector library in the project's lib folder -->
            <dataSourceDefinition>
                <driverClass>com.mysql.jdbc.Driver</driverClass>
                <url>jdbc:mysql://localhost:3036/test</url>
                <user>root</user>
                <password>root</password>
            </dataSourceDefinition>
        </connectionPolicy>
        <loadConstraints maxConcurrentConnectionsPerNode="5" />
    </connectivity>

    <!-- Replace this with appropriate procedures -->
    <procedure name="select"/>

</wl:adapter>

和adapter-impl.js

var statement = WL.Server.createSQLStatement("select * from categorie");
    function select(statement) {
        return WL.Server.invokeSQLStatement({
            preparedStatement : statement
        });
    }

我下载了连接器.jar驱动程序并在server/lib文件夹中找到它。我不明白可能出现什么问题......

我解决了这个问题。我在.xml文件中编辑了url的端口（是3306而不是3036），我还更正了select(statement)中的函数select()。

在两个文件下方更正了。
